Subject: Re: linux-next: manual merge of the security-testing tree with
 Linus' tree

Hi Stephen,

looking at commit ffa8e59df047, it also adds

+extern const kernel_cap_t __cap_full_set;

under __cap_empty_set.  My trees are a bit screwed up so I'm not sure if
that gets later removed, but I just wanted to make sure you didn't
accidentally drop that.

Otherwise looks good, thanks and sorry for the noise.

thanks,
-serge
